Patented Sept. 25, 1945 UNITED STATES, PATENT OFFICE BEAK AND WING TRIMMER AND CAUTER- IZER FOR, FOWL AND THE LIKE James Lyon, SanDiego, Calif. Application August 11, 1944, Serial No. 549,031 Claims. (01. 12s' s03.10)

" This invention relates to a means for trimming beaks and ing clipping .of poultry and other fowl, and it consists in the constructions, arrangements and combinations herein described and claimed.

-It' is a particular object of the invention to provide a trimming device wherein a beak or wing portion of fowl may be severed by means of a heated cauterizing edge element.

It is also an object of the invention to provide means for regulating the amount of heat supplied to the cauterizing edge to meet various conditions as well as to lengthen the period of use of the cauterizing edge, since excessive constant heat will tend to reduce the life of the edge element. V v

More specifically it is an object of the invention to provide an apparatus of the kind indicated in which a supporting base is provided upon which a carriage is swingably mounted, resiliently supported in elevated position, the carriage including a cauterizing edge cooperalble with a water-cooled anvil upon downward movement of the carriage.

Additional objects, advantages and features of invention will be apparent from the following description considered in conjunction with the accompanying drawings, wherein Figure 1 is a perspective view of the device.

Figure 2 is a vertical section therethrough.

Figure 3 is a top plan view, partly in section.

Figure 4 is a cross section on the line 4-4 ,of Figure 2.

Figure 5 is a front elevation, partly in section.

Figure 6 is a plan view, of a modified form of cauterizing edge and mounting therefor.

Figure 7 is an edge view thereof.

There is illustrated a machine Ill comprising a base frame II, which in the present instance, is shown as a rectangular trough defined by integrall connected side walls I2 and bottom wall I3. The side walls I2 are each provided with a horizontal flange I4, for support of a carriage I5.

The carriage I5 consists of a top wall I6 and respective side walls H, the over-all width being such as to permit free introduction within the trough portion of the base II. The length of the'carriage I5 is substantially shorter than the base II and at the rear end thereof a leaf I8 of a hinge I9 is secured, the other leaf of the hinge being connected to a plate 20 extended transversely across the flanges, I4. The plate 20 is detachably mounted upon the flanges which in the present instance is accomplished by providing longitudinal slots 2| in the plate 20 the flange I4 being apertured, and through the slots and apertures a .bolt 22 is extended to receive a wing nut" 23. By the provision of the slots, it will be apparent that longitudinal adjustment of the carriage with respect to the'base is made possible.

At the front end of the base II, an upright frame piece 24 is welded or otherwise secured to each of the flanges I4. The width of these frame pieces is greater than the width of the flanges thus forming a base upon which an anvil may be mounted, as will be described. As may be seen 'i'nFigure 1, the frame pieces 24 define an opening 25. The upper ends of the frame pieces 24 are formed with right angular extensions 26 each of which is provided with an opening for receptionof a threaded bolt 21. A strip of heat-resisting material 28 is 'extendedacross. the extensions 25, the strip being aperture-d to accommodate the bolt 21, an langularly shaped finishing plate 29 being disposed upon the strip andlikewise aperture'd to receive the bolt 21. A wing nut 30 is engaged upon the'bolt for'the purpose of adjustment of the carriage, aswill be described. A helical spring 3| is secured to the head of the bolts 21, the opposite end being attached to the forward end of the carriage. I5 as at 32. It will be apparent that the tension of the spring may be varied by adjusting the wing nuts 30.

A front heat guard 33 is detachably'mounted upon the frame piece 24 by means of screws 34, the guard stopping short of an anvil '35 mounted transversely across the flanges I4, to the rear of the frame piece 24. p As maybe seenin Figure 2 and 4, the frame pieces 24 are formed with right angularly disposed supporting feet 36 apertured to receive respectivebolts 37 which in conjunction with a clamp plate 38 function to secure the anvil 35 in proper position upon the base. illustrated as having a leg 39 adapted to rest upon respective feet 33 and with the anvil engaged beneath the plate tightening of the bolt will firmly secure the anvil. The plate 38 is of such length as to permit adjustment of the anvil longitudinally of the base, which is made possible by merely loosening'the bolts 31 I The device is constructed for either hand or foot operation, as will now be described. Upon the carriage I5 at the forward end, a fulcrum 40 is mounted, the upper end of which swingably -mounts a lever 4i, the pivot 42 being next adspective side walls I2 of the base; It will be seen The clamp plate 38 is that by exerting a downward pull upon the handle 43, a corresponding movement will be imparted to the carriage l against the tension of the springs 3|, the latter functioning to return the carriage to normal position upon release of the handle. The mounting of the lever 4| and the carriage is such that alimited lateral movement ma be imparted to the carriage by moving the lever laterally from side to side which is of importance when severing a beak of substantial thickness, since any tendency to crush the beak is obviated. Inthe event that it is desired to operate the carriage by means of a foot treadle or the like, a pull cord 46 is secured to a bracket 41 fixed to the underside of the carriage IS, the other end of the cord being connected to afoot treadle not shown. A downward pull on th cord will efiect a similar movement of the carriage. At the front end of the carriage a heater unit 48 is secured by means of bracket 49. The heater in the present'instance consists of an insulator body 50 within which a heater coil 5| is mounted, energized through. wires 52 and 53, the latter being connected to binding posts 54 and 55, respectively. A cuttingand cauterizing blade 55 is mounted in the body 50 by means of bolts 51 maintainingthe blade closely adjacent the coil 5i for heating purposes. The blade 56 projects beyond the periphery of the body 50 so as to cooperate with the anvil 35 to effect the cuttingof a beak disposed upon the anvil. It will be noted that the blade 56 may be readily replaced by removing the bolts 51.

Upon the carriage l5 an'electrical socket 58 is secured within which there is removably mounted a resistance element 59-, of conventional construction, The resistor and the heater unit are connected in series, as may be seen in Figure 4. A

the resistance or heater strip 10. This modified form of cutter may replace the heater coil 5| and associated cutter, and to this end the base 13 is provided with openings 11 through which the bolts 51 may be extended and secured to the bracket 49. A 4-V-100 watt transformer is preferably used in conjunction with this type of blade and heater, replacing the resistor 59, electrical connection between the transformer and the heater being made with respective binding posts 18 on the legs H and 12,

. gether with downward pressure will quickly and neatly sever the beak. Where a large number of fowl are being operated on, the anvil will 'be heated to an uncomfortable degree, and to reduce the temperature, cooling water may be fed to the nected to thebinding post'54, while the other line f 62. is connected to a binding post 63 of the socket 58. A line 64 is secured between the binding post .55 and a post 65 of the socket, completing the circuit to the heater unit.

'It is desirable in many situations, to have an illumination means, so that the operation of trimming a beak or wing-tip is clearly discernible andas shown, a small bulb 66 is mounted in a ing 'post: 63 and through a lead 69 connected to the base of the socket and the bindin post 54.

anvil b means of a hose [9, the flow of water being controlled by'a suitable clamp 80.

In the case of wing clipping, the tip is re.- .moved at the first joint. It is advisable during this operation to remove the'heat guard 33 in order to afford ample clearance and visibility, which is especially true with full-grown fowl.

While I have shown and described the invention specifically, this is by way of illustration only, and I consider as myown all such modifications in construction as fairly fall within the scope of the appended claims: '1.

'Iclaim: a
